            Bug ID: 298952
          Severity: crash
           Version: 4.8.2
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: kmail is crashing while moving IMAP folders
    Classification: Unclassified
                OS: Linux
          Reporter: salem at saberhagen.de
          Hardware: Compiled Sources
            Status: UNCONFIRMED
         Component: general
           Product: kmail2

Application: kmail (4.8.2)
KDE Platform Version: 4.8.2 (4.8.2) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.3.3-gentoo-Saberhagen x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
- What I was doing when the application crashed:

I just dragged/moved a folder from one folder to another. This worked and i can
see the folder in the new folder. But then after 5-10 seconds the client
crashes.

- Unusual behavior I noticed:
The move is working but the client is crashing after the folder list was
updated.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
